Full power WKRC in Cincinnati tried this years ago when dial up internet was
the norm and gave up because the bandwidth was just not there. And with Cell
phones acting at hot spots, there is even less need for it. It is probably a
manufacture trying to sell a product and after they roll it out in a few
locations, they will go “wait, it doesn’t work”.

Just want everyone to be aware that the PBS consortium is looking to lock this
up and have apparently been on the move.
It seems LPTV gets the short end most of the time.

The problem is it takes a lot of bandwidth to do internet. A TV station may
be able to offer 16 MBits down, but that is to one subscriber. You can do more
with your cell phone. You can divide up the areas with high directional
antennas, but it is just not feasible. The best way to do it is with 2.4 & 5.8
GHz license-free networks. The beam is narrow and the equipment to do it is
cheap. If a city wanted to, they could run a fiber down a street and put small
5.8 GHz link on every couple of telephone poles. The range is limited and
fairly secure. But even that will load up quickly as I saw in Bowling Green KY
when we tried to do a 5.8 GHz STL link. There are a lot of folks using this
technology.
What I have seen is LPTV operators leasing streams to school systems to send
out educational video to Covid locked down students. Zoom meetings are great,
but most internet systems cannot handle 100,000-200,000 students and teachers
trying to send live video. We are seeing school systems go back to the
educational TV of the 60’s and 70’s where a teacher sets up a camera and
teaches a class. Questions can be handled by low-bandwidth texting. And if a
lot of teachers are trying to send out their teachings during the prime
8am-4pm, Wal-Mart and others have set top boxes that will record off air for
under $25 (emetic AT103C). Plus a flash stick in the front and record your
lessons on a $5 stick. (By the way, a real good tool for a station to have as
well.)
So yes, we LPTV operators do have an answer to school systems on how to
handle remote learning. We just have to go to the school systems and show them
how to do it. Teacher can record a lesson on their cell phone if they do not
have a video camera and send it to a video server via mp4.

J did t know if any of you knew anything about datacasting.
The public television industry is hedging their bets on success and future
funding by working their way knot the good graces of stated educational
departments by “offering” this great technology of embedding data into their tv
broadcast stream and getting school j formation and homework to students in
rural areas.
Of course they’re lining of big deals with most states as an exclusive thing
that public tv can do. However most states are t 100 percent covered by public
tv signals.
A company called Westpond has the equipment but a guy named Mark O’Brien from
Spectrarep has locked them up so they won’t sell to anyone else.
They want to control it all. However this really isn’t something special. All
tv stations could do it
Indiana just gave a $20 million grant to make it happen. And you know it won’t
take $20 million to do this. Basically it’s giving up a subchannel and getting
word files, PDFs and some video into the tv stream and then providing a box to
every student at home and an antenna to get the station and a way to “download”
the data from the stream.
If we could figure a way to do this I think this would be a sustainable revenue
stream for a few years to come or u til rural broadband becomes a reality.
Curious on your thoughts?
